* don't allow stripe with just one subvolumeAmar Tumballi2009-11-261-1/+7
| | | | | | | | | | | | stripe code assumes in many places that it will have more than one subvolume, but the strict check was not there in init, hence, if somebody configures stripe with just one subvolume, it will cause many fops with frame loss.

* fixes in stripeAmar Tumballi2009-11-161-2/+3
| | | | | | | | | | | | | * fix in stripe readv, so that a read request which falls in two (or more) subvolumes, depending on stripe-size works fine. * fix in stripe_setattr_cbk, where 'postop' stat structure was returning wrong 'st_size'.

* strict check of extended attribute flags while opening a striped fileAmar Tumballi2009-06-112-68/+223
| | | | | | | | | | Added a fd_ctx structure for stripe, which takes care of understanding the extended attribute flags, and opening the right blocks in order (to make sure the read/write operations happen in order). Helps to handle situations like accidentally adding subvolumes to stripe, etc Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
